TECHNICAL FIELD

The present invention belongs to the technical field of furniture, and in particular relates to a bar-shaped iron frame bed with a fixing structure of a fillet tube.

TECHNICAL BACKGROUND

An iron frame bed, also known as a bunk bed or an apartment bed, is derived from a wooden frame bunk bed. The iron frame bed is characterized by: being easily disassembled, assembled and installed, strong stability, effective use of vertical space, and greatly increasing space capacity. The iron frame bed is widely used in various collective dormitories, such as a student dormitory, a factory/unit dormitory, a construction site dormitory, etc. The process of the iron frame bed is relatively simple and divided into: a material, welding, painting, etc. The production requirements of the iron frame bed are as follows: an excellent welding process, no desoldering, blowholes, pinching, weld beading, spattering, undercutting, a ripple height of a welding scar being not more than 1 mm. A corner of the iron frame bed and welding are rigorously inspected, otherwise it is prone to scratch clothes and a quilt and other phenomena. The iron frame bed of the bunk bed is very important in the selection of materials. The thick steel iron frame bed is safer and more stable in use. A cross rod and a vertical column of the iron frame bed in the prior art are mostly connected by welding. After welding, a bed body is relatively strong.
